This document discusses new models of employee performance and their implications for employment relations. It summarizes two prominent models of performance - a task performance and citizenship performance model proposed by Borman and Motowidlo, and an eight-component model proposed by Campbell. Both models attempt to identify broad dimensions of performance that allow for greater generalizability across jobs and occupations. The document argues that citizenship performance, which involves maintaining the interpersonal environment, contributes significantly to overall performance ratings and organizational outcomes, though it has received less attention than task performance.
